When would you use the -r option with the cp command?

You would use the -r option (or --recursive) with the cp command when you want to copy entire directories along with all their contents, including subdirectories and files.

Situations to Use -r:

1. Copying Directories: When you need to duplicate a directory structure, such as backing up a project folder.
2. Transferring Data: When moving data from one location to another while maintaining the original directory hierarchy.
3. Organizing Files: When you want to reorganize your files by copying entire directories to new locations.

Example Usage:

cp -r source_directory destination_directory

This command copies source_directory and all its contents to destination_directory.
